Referring more particularly to the drawings, the improved fastenerelement feeding mechanism of the present invention is shown incorporatedwith a conventional fiat button sewing machine of the Singer type whichwill not Edhhidh be described in detail as the construction andoperation of such a machine is well known to those skilled in the art. Amachine of such type is shown in the US. patent to Horton, No.1,051,998, dated February 4, 1913. Referring more particularly to FIGS.1 and 2, such a machine comprises generally a fiat 'base or bed plate 2upon which there is mounted a standard 3 supporting a horizontallyextending bracket-arm 4 which terminates in a hollow head 5 wherein theneedle-bar 6 carrying a needle 7 is journaled for reciprocation.

The main shaft 8 is journaled in the bracket-arm 4 and provided at itsforward end with the usual take-up cam cylinder having a crank-pinconnected by means of a pitman with a lateral stud upon the needle-bar6. The needle 7 cooperates with a shuttle in the base in a well knownmanner to form stitches and secure a fastener element E to a garmentpart G.

For the purpose of this disclosure, the relative jogging or stitchpositioning movements between the stitch forming mechanism and thefastener element holder are obtained by vibrating the fastener elementholding member substantially in a manner as shown in the aforementionedpatent. The work holder of this type comprises a lower member in theform of a work supporting bar 13 mounted for movement over the bed 2. Tothe forward end of this bar 13 is secured a work-supporting plate 14which rests upon the foot-like throat-plate 15 of the machine and isadapted to slide freely thereover. With this work-holder, there isprovided a fastener element holding member which includes an uppermember or bar 16 pivotally supported at its rear end by a bracket 17 andpressed toward the bar 13 by means of the usual leaf-spring 18, as moreclearly shown in FIGS. 1, 2, 3 and 5 of the drawings.

On the forward end of this upper bar 16, there is positioned a clampingfoot 19 having a pair of open ended slots 20 in the extreme outer endthereof for receiving the needle '7. (3n the underside of this foot 1%adjacent the inner ends of the slots 20, there is positioned a springclip-like member 21 for receiving and holding a fastener element E whileit is being stitched to the garment part. There is also carried by thisupper bar 16 adjacent the inner end of the clamping foot 1%, afinger-like member 22, the free end of which cooperates with anoutwardly projecting lifting member 23 carried by a verticalreciprocable bar 2d positioned in the head 5 parallel to the needle-bar6.

The Work supporting bar 13 is suitably secured at one end thereof to thebed plate 2 of the machine both for longitudinal and lateral movementthereover. On the inner end of this work supporting bar 13 there ismounted a cam roller (not shown) which cooperates with a cam race (notshown) on the inner side of the cam-wheel 3%. This cam wheel uponrotation thereof is adapted to impart a lateral and longitudinal joggingmotion to the work supporting bar 13 together with the fastener elementholding bar 16 mounted thereon in a manner similar to that shown anddescribed in the aforementioned patent and for a purpose hereinafter tobe described.

According to the present invention, there is provided a verticallyextending oscillating lever-like member 31 having one end thereofpivotally connected to the base of the machine, as at 32. There isprovided a horizontal arm 33 having one end thereof secured to thelever-like member, as at 34. There is attached to the free end of thisarm 33, a treadle-chain 35 with the opposite end of this treadle-chainattached to a treadle (not shown).

intermediate the length of this arm 33, there is positioned a rod-likemember 36 having the lower end thereof pivotally attached, as at 37, toa fixed bracket member 38. The upper end of this rod-like member 36 isslidably mounted in a bearing member 39 carried by the arm 33.

Q There is positioned around this rod-like member 36, a compression coilspring 40.

On the upper end of the oscillating lever-like member 31, there issecured a cam member 41 having a cam-groove 42 arranged in the innerside thereof. On top of the horizontal bracket-arm 4 of the machine,there is mounted an elongated yoke-like lever 43 which is pivotallyattached to this bracket-arm 4 intermediate the length thereof, as at44. On one end of this lever 43, there is mounted a cam-roller orfollower 45 which is positioned in the camgroove 42 of the cam member41. The opposite end of this lever 43 is connected to the upper end ofthe vertical reciprocable bar 24-, as at 46.

To one side of the needle 7 and opposite the ends of the bar 13 and foot19, there is positioned an elongated longitudinally disposed guidemember 50 having a longitudinally extending rectangular shaped channel51 in the upper side thereof. The inner end of this guide member 50terminates adjacent the clamping foot 19 directly opposite thespring-like clip member 21 carried thereby, as more clearly shown inFIGS. 3, and 7 of the drawings. There is positioned in this channel 51for reciprocable movement therein, an elongated feed bar 52.

Above this guide member 59 there is mounted vertically, an elongatedmagazine 53 substantially rectangular shaped in cross section forholding a supply of fastener elements E positioned one on top of theother, as shown in FIGS. 1a, 3 and 5. The lower end of this magazine isopen and communicates with the channel 51 in the guide member 50 and thefastener elements E move successively from the magazine to the channelby the force of gravity.

Now referring more particularly to FIGS. 1, 3, 4, and 6 of the drawings,there is provided a rod-like lever 55 having one end thereof pivotallyconnected to the oscillating lever-like member 31 intermediate thelength thereof, as at 56. The opposite end of this rod-like lever 55 isslidably connected to an oscillating bearing member 57 mounted on theouter end of a crank lever 58. On the outer end of this rod-like lever55 there is positioned therearound, a compression coil spring 59 havingone end abutting a stop member 60 and with the opposite end abutting theside of the bearing member 57.

As more clearly shown in FIGS. 3, 4 and 6, there is positioned on theopposite end of the crank lever 58, a sleeve-like bearing member 61through which a bolt 62 extends for securing it to a bracket 64 attachedto one side of the machine. There is provided another lever 65 havingone end thereof secured to this sleeve-like bearing 61. In the oppositeend of this lever 65, there is provided a slotted opening 66 into andthrough which a pin 67 extends which pin is mounted in the outer endportion of the elongated feed bar 52 in the channel 51 of the guidemember 50.

For the purpose of illustration, in connection with the use of myimproved feeding mechanism, there is shown a fastener element E, as moreclearly shown in FIGS. 7 and 8 of the drawings, which is the eye elementof a hook and eye assembly for use primarily on waistbands and the likeof mens and womens trousers and skirts. Such a fastener element consistsof a flat plate-like member having two pairs of holes therein with onepair arranged at each end through which the stitches pass to stitch theelement to a garment part or other article. To sew such an element, itwill be understood that the element and garment part necessarily willhave to be moved or jogged relative to the needle 7 in order that agroup of anchoring stitches pass through the holes and around thatportion of body of the element positioned between each respective pairof holes in the form of a tacking operation. Such jogging movement ofthe fastener element relative to the needle in a sewing machine is wellknown to those skilled in the art.

Now the mechanism for moving laterally the work supporting bar 13 andthe bar 16 together with the clamping foot 19 carried thereby will bedescribed. It will be understood that the inner end of the worksupporting bar 13 is attached to the lower end of a vertical shaft 711which is suitably journaled in a bracket 71 mounted on the base 2 of themachine. On the underside of the base 2, there is mounted alongitudinally extending oscillating shaft (not shown) having one endthereof geared to the vertical shaft 7 0 below the bracket 71 foroscillating this shaft '70. Intermediate the length of thislongitudinally extending shaft, there is mounted thereon a lateral crankarm '73 having the outer end thereof pivotally connected to the lowerend of a pitman '74. The upper end of this pitman '74 is pivotallyconnected to a pin 75 positioned in a slotted opening '76 in one end ofa crank arm 77. This crank arm 77 is pivotally attached intermediate itslength to a stud shaft 7 8 arranged on the upper end of the bracket 71.C=n the opposite end of this crank-arm 77, there is positioned a pin '79which extends through a slot 81) arranged in the lower end of an uprightarm 81. The opposite end of upright arm 81 is pivotally attached to theinner end of the lever 43, as at 82, opposite the cam-roller 45. Thereis mounted on the side of this upright arm 81, a roller stud which isdisposed in the cam groove in the cam wheel 31?. The rocking of thecrank-arm transmits lateral motion to the member 16 through the pitmanarm '74 and the oscillating shaft (not shown) in the base of the machineaffording a universal joint connection so as to permit the freelongitudinal as well as lateral movement of the member 16 in a mannerwell known to those skilled in the art. There is provided an elongatedhandle member 83 having one end thereof connected to the end of thiscrank-arm 77 for manually actuating the lateral jogging movement of thework supporting bar 13 in a manner and for a purpose hereinafter to bedescribed.

While the present fastener element feeding mechanism has been designedand is illustrated in connection for feeding the eye element of a hook'and eye fastener assembly, it will be understood that the mechanism maybe conveniently modified for feeding most any fastener element of thistype regardless of size or shape.

Operation Having described the construction of my improved fastenerelement feeding mechanism, it functions in the following manner. It willbe assumed that a garment part G or other article is in readiness to bepositioned on the work-supporting plate 14 for stitching a fastenerelement E thereto and that the sewing machine is in readiness foroperation.

The treadle connected to the treadle-chain 35 is manually actuated bythe machine operator whereby the oscillating lever-like member 31together with the cam member 41 carried thereby is moved to the left, asshown in FIG. 1, about its pivotal connection at 32. In so doing, itwill be seen that in the initial movement, the inner end of theelongated lever 43 is moved downwardly about its pivotal connection 44due to the cooperation of the camroller 45 arranged on the end of thelever 43 with the cam-groove 42 in the cam member 41. As a result ofsuch movement, the opposite or outer end of this lever 43 will moveupwardly which will in turn move the presser foot bar 24 upwardlytogether with the projecting member 23 carried thereby. When the presserfoot bar 24 moves upwardly, it will be'seen that the projecting member23 carried thereby contacts the finger-like member 22 mounted on the bar16 thereby lifting the outer end of this bar together With the clampingfoot 19 arranged therewith from its position of rest on theworksupponting plate 14 so that the space between the under side of thisclamping foot 1% and the spring clip-like member 21 is in alignment withthe end of the feed bar 52, as more clearly shown in FIGS. 3 and 5 ofthe drawings, and in position for receiving a fastener element E fromthe end of the channel 51 in the guide member 59.

As the oscillating lever-like member 31 together with the cam member 41carried thereby continues to move to the left, as shown in FIG. 1, therod-like lever will also be moved to the left due to its pivotalconnection therewith at 56. In such movement, the stop member 66arranged on the end of this rod-like lever 55 will eventually throughspring 59 build up sufiicient force against the oscillating bearingmember 57 arranged on the outer end of the crank lever 58 to move it tothe left about its pivotal connection till, 62. This crank lever 58 inturn will move the elongated lever to which it is connected forwardly,as shown in FIG. 3. As a result, the feed bar 52 in the channel 51 ofthe guide member 50 is moved forwardly due to its connection at 67 withthe lever 65. In such movement, this feed bar 52 will strike a fastenerelement E at the lower open end of magazine 53 in the channel 51 andmove it toward the clamping foot 19 and to position in the space betweenthe under side thereof and the spring-clip 21 whereby it is heldsecurely in position on the clamping foot. The garment part G is thenpositioned on the work-supporting plate 14 in under the clamping foot 19in readiness for g sewing.

After the fastener element E has been nested in position in the end ofthe bar 16, the treadle is released by the operator thereby permittingthe oscillating lever 31 together with the cam member 41 carried therebyto return to its retracted position and to move to the right as shown inFIG. 1, due to the action of coil spring 40 on the rod 36. In suchmovement, it will be seen that the feed bar 52 will be moved rearwardlyin the channel 51 in the guide member 50 to its retracted positionthrough the action of the lever 65, the crank lever 58 and the rodlikelever 55. As the oscillating lever-like member 31 continues its movementto the right, the presser foot bar 24 will move upwardly due to theaction of the elongated lever 43 and the cam roller 45 on the endthereof in cooperation with the cam-groove 42 in the cam member 41thereby permitting the clamping foot 19 together with the fastenerelement E positioned therein to move to position on top of the garmentpart G in readiness for sewing due to the action of the spring 18.

The machine is then started in the usual and well known manner for apre-determined number of stitchforming operations. It will be understoodthat as the needle 7 reciprocates in one of the slots 20 the fastenerelement holding bar 16 and the work-supporting bar 13 are subjected to alongitudinal jogging movement so that the needle 7 moves through therespective pairs of holes alternately in one side of the fastenerelement E in the clamping foot 19 so as to stitch one side of thefastener element to the garment part by means of a bar tack, as shown inFIG. 8 of the drawings.

After one sewing or tacking operation has been completed, the worksupporting bar 13 together with the bar 16 and the clamping foot 19carried thereby is moved or jogged laterally so as to position the otherslot 20 and the other two holes in the fastener element E opposite theneedle so as to tack the other side of the fastener element to thegarment part G. This is accomplished by the operator by moving thehandle 83 downwardly. In such movement of this handle 83, the worksupporting bar 13 will be shifted to the left, as shown in FIG. 3, so asto position the right hand slot 2%! in the clamping foot 19 opposite theneedle '7 in readiness for sewing. This movement of the :ork supportingbar 13 is accomplished through the action of the longitudinallyextending shaft in the base, the shaft 76, the pitman '74, and thecrankarm 77. The other side of the fastener element E is then stitchedto the garment part G with the stitches passing through the respectivepair of holes alternately, as before, so as to stitch that side of thefastener element E to the garment part. After this tacking or sewingoperation has been completed, the handle member 83 is moved upwardly soas to shift the Work supporting bar 13 together with the clamping footcarried thereby to the right and to its initial position in readinessfor the receiving and sewing of another fastener element to a garmentpart.

It will be understood that when the crank-arm 77 is moved initially thepin 79 carried thereby will move to the end of the slot 80 in the lowerend of the upright arm 31 so as to lock the cam-roller 45 andoscillating lever-like member 31 against movement whereby accidentalfeeding is prevented of a fastener element E to the clamping foot 19when it has been shifted to the left. That is to say, a fastener elementcannot be fed to the clamping foot 19 when it is positioned for thesecond sewing operation. This completes one cycle of operation of themachine and the fastener element feeding mechanism.

As a result of my invention, it will be seen that there is providedsimple and inexpensive mechanism for feeding automatically fastenerelements or members successively to position opposite the needles of asewing ma chine where they are held firmly and securely in positionwhile they are being sewn to a garment part or other article. It will beseen further that the activation of the fastener element holding meansand the delivering of the fastener elements successively thereto are intimed relation so that the fastener element holding means is positionedopposite the fastener delivery means and in alignment therewith at theproper time for receiving the fastener elements, both of these membersto be activated by a common means, namely, the oscillation lever-likemember 31 which is one of the most important aspects of the invention.

While I have shown and described an embodiment which my invention mayassume in practice, it will be understood that this embodiment is merelyfor the purpose of illustration and description, and that other formsmay be devised within the scope of my invention as delined in theappended claims.
